If licensed at your site, N4 checks vessel strength and stability and handles weights and moments during the vessel planning process. For example, you can do the following:
Check the vessel's strength and stability (on page 1)
Display stress curves to highlight problem bays
Change the tankage levels (on page 1)
Change the water density (on page 1)
Add extra weights (on page 1)
Print and review stability reports and Cargo weights reports
